He believed me to be sleeping.

My brother is a huge pervert. He always has been. Ever since he moved back in after his girlfriend dumped him, he's been sneaking into my room. He usually starts by groping me, and I don't react because I'm too exhausted, but this time he decided to grope me. I didn't have a blanket because it's hot, and my air conditioning isn't the best. But I don't sleep naked. He massaged me through my panties until I was wet, then he slid his head between my legs and started licking. He easily found my clit through the thin fabric of my panties, and in the split second it took him to move them to the side and start sucking, I made a noise. He must have known I was awake. I couldn't stop convulsing as my filthy older brother licked my pussy. I came, and he wouldn't stop. He even slipped a finger inside me and groaned when he felt how tight I was. The way he roughly whispered, "Oh fuck," before spitting on her, still replays in my head. Suddenly, he sat up and must have been stroking his cock the entire time he licked me, because he came all over my pussy, then started cleaning up the trail with his tongue. And then he simply pulled out, wrapping me around me and adjusting my underwear. He didn't fuck me, but the whole experience made me wish he had.
